The Dyke JD-2 Delta is an unconventional American blueprint aircraft for amateur construction. It offers space for one pilot and two passengers. The JD-2 is the most widely built civilian tailless aircraft .
history
The machine is a design by the couple John and Jenny Dyke from the 1960s. The prototype first flew on July 18, 1966. The machine was not offered as a kit, but John Dyke only marketed the construction plans. The relatively high cruising speed made the small machine particularly interesting. In total, over 50 of these aircraft were completed and approved. At least ten planes are still flying and another dozen are being restored. In the 1970s, Robin became interested in manufacturing the machine under license in Europe. In contrast to the cockpits of the construction plan aircraft, which were glazed with sheet material, the prototype had a more elegant, spherically blown canopy. A JD-2 was also used by NASA to study the characteristics of a delta wing in aircraft tow.
construction
The load-bearing structure of the entire aircraft consists of tubular steel that is planked with fiberglass panels or covered with fabric. The outer wings are removable and can be attached to the center piece for road transport. The pilot's seat is in the center of the front of the cockpit, behind it is a bench for two normal or three smaller people. The special feature of the aircraft is its tailless design and the fact that the fuselage is also used to generate lift. The tripod undercarriage is retractable on most machines. It is controlled via elevons and rudder. A small horizontal stabilizer at the tip of the vertical stabilizer is optionally available for trimming purposes.
